3
Download audio
FFmpeg extracts audio locally. Preview in the browser, then download.

Choose the Right Audio Format

The best format depends on where the extracted audio will be used. A higher bitrate can preserve more detail during encoding, but it cannot recover quality that is missing from the video's original audio track.

Format	Best for	What to expect
MP3	General playback and sharing	Broad compatibility with selectable bitrate
M4A	Apple devices and efficient storage	AAC audio in an M4A container
OGG	Open-format workflows	Vorbis compression with good quality per byte
WAV	Editing in a DAW or audio editor	Uncompressed PCM and a much larger file

Audio Quality, Bitrate, and File Size

For spoken audio, 96–128 kbps MP3 is often sufficient. A 192 kbps MP3 is a practical default for music, podcasts, and mixed content, while 256–320 kbps produces a larger file for sources that contain useful high-frequency detail. WAV avoids another lossy compression step, but it does not make a compressed source sound better.

Loudness normalization targets a more consistent listening level and controls peaks. It is useful for lectures, interviews, and recordings with uneven volume, but it changes the signal and requires additional processing.

Browser Processing and Practical Limits

The browser must hold the source video, the WebAssembly audio engine, working data, and the finished audio at the same time. Available device memory therefore matters in addition to file size. Close memory-heavy tabs, keep this page open during extraction, and use a shorter video if a large project fails on a phone or low-memory computer.

Why extract audio in the browser?

Cloud converters upload your entire video to a remote server. This tool uses FFmpeg WebAssembly on your device — private, free, and works without an account. Ideal when you want audio from a clip without sending the file anywhere.

Continue Your Audio and Video Workflow

After extraction, use the Audio Cutter to keep only the section you need, the Volume Booster to adjust loudness, or the Audio Converter for another file type. You can change tempo or pitch with the Audio Speed Changer and combine finished clips with the Audio Joiner. To reduce the original video instead, use the Video Compressor.

Frequently asked questions

Tip: Use 192 kbps MP3 for music and podcasts. Switch to WAV if you plan to edit further in a DAW.
